Specification of Letters Patent.

Patented Feb. 2, 1915..

The objects of .my invention are to provide a means of making andsecurely fastening or looking a Babbitt journal bearing to one end of aconnecting rod and to a cap provided therefor in such a manner as toprevent the rotation of or separation of the bearings from theconnecting rod or cap thereof.

1 attain these and other objects by the mechanism illustrated in theaccompanying drawings, in Which:-

Figure 1 is a plan view of the connecting rod showing a cap securedthereto. Fig. 2 is a side elevation of Fig. 1 partly in longitudinalsection. Fig. 3 is a sectional view of the cap on the line A-A of Fig. 1Fig. 4 is a sectional view of the cap on the line BB of Fig. 1.

In the drawings reference numeral 1 represents a connecting rodpreferably made I shape in cross section. An eye 2 is formed on one endto provide a journal bearing 3 or to receive a sleeve (not shown) whichis held in place by compressing the lugs 4 and 5.

My invention primarily consists in forming an enlarged ring or eye onone end of the connecting rod and beveling or inclining both sides 7 and8 toward the plane of the rod and forming a series of notches 9 at.predetermined points in the beveled surfaces 7 and 8. The ring is out intwo parts providing an adjustable cap 10 and a semicircular part 6. Theparts are fastened together by bolts 11 which pass through suitable lugsformed on the cap 10 and the part 6.

' To construct the Babbitt bearings and selcure them to the connectingrod and cap a shaft is inserted in the center of the part 6 and the cap10 and metal (preferably babhitt) in a liquid state is poured or forcedand the projecting parts around the shaft forming the bearings 11 12 and13 which close upon and interlock with the beveled portions 7 and 8thereby preventing the Babbitt bearings from separating from the part6or cap 10. The liquid metal also flows into the notches 9 forming lugson the bearings which fit said notches, thereby preventing the bearingsfrom any tendency to rotate upon the part 6 or cap 10.

What I claim is 1- 1. A connecting rod provided with a semicircular parton one end, a complementary cap part adjustably secured thereto, both ofsaid parts being provided-with bevel sides with notches formed therein,bearings to engage said bevel sides and notches, as and for the purposedescribed.

2. A. connecting rod provided with a semicircular part on one end, acomplementary cap part adjustably secured thereto, both of said partsbeing provided with bevel sides with notches formed therein, bearings to'engage said bevel sides and notches, said parts also being providedwith inclined inner surfaces.

8. A connecting rod having one end formed with bevel sides and notchesto engage and receive a bearing, a bearing constructed to fit said bevelsides and notches, a complementary cap adj ustably secured to the end ofsaid connecting rod, said cap being provided with bevel. sides andnotches to receive a bearing, a bearing adapted to engage the bevelsides and notches of said cap, as and for the purpose described.

4. A connecting rod having one end formed with bevel sides and notchesto engage and receive a bearing, a bearing constructed to fit said bevelsides and notches, a complementary cap adjustably secured to the end ofsaid connecting rod, said cap being provided with bevel sides andnotches to receive a bearing, a. bearing adapted to on D said cap andend of the rod being provided with inclined inner surfaces.

in testimony whereof ll afiix my signa ture in presence of twowitnesses.
